摘要:
针对无线协作多播网络中的能量效率问题，设计了一种基于功率控制的能效优化策略。通过采用功率控制因子 来限制系统总的能耗，按照最小信噪比原则进行中继节点选择，来增加系统吞吐量。该策略合理分配了基站和中继节点的功率， 扩大了系统的覆盖范围，提高了发射效率。仿真结果表明了，与传统传输机制相比，完全搜索算法和变功率中继选择算法在效 率方面有了较大提高，而时间分配算法则找到了最优的转发时间比例。
Abstract:
Aiming at solving the problem of energy efficiency in wireless multicast network, one energy efficiency optimization strategy based on power control is designed. In order to increase the system throughput, the system overall energy consumption is limited through the adoption of power control factor and the principle of minimum SNR relay node selection. The strategy has expanded the coverage of the system, and improved the efficiency of the launch, by the allocating the power of the base station and relay nodes reasonably. The simulation results show that, the full-search algorithm and variable-power relay selection algorithm has improved system efficiency greatly, compared with the traditional transmission mechanism, while the time allocation algorithm has found the optimal time ratio of forwarding.
